BENJAMIN IIOIVARTH TI-IIVAITE, OF LONDON, ENGLAND, ASSIGNOR OF ONE-HALE TO FRANK LAOROIX GARDNER, OF SAME PLACE.
APPARATUS FOR SEPARATING DUST FROMBLASTJURNACE GASES.
SPECIFICATION forming part of Letters Patent No. 617,618, dated January 10, 1899.
Application filed April 4, 1898. Serial No. 676,391. (No model.)
To all whom it may concern.-
Be it known that I, BENJAMIN HOWARTH THWAITE, civil engineer, a citizen of England,
residing at No. 29 Great George street, Westminster, London, England, have invented certain new and useful Improvements in Apparatus for Separating Dust from BlastFurnace Gases, of which the following is a specification.
This invention relates to means of separating dust from blast-furnace gases as they descend the downcomer or pipe by which they are led from the top of the furnace, as I shall describe, referring to the accompanying drawing, which is a vertical section of the downcomer of a blast-furnace provided with dust-separating apparatus according to my invention.
- A is the downcomer, having its lower part inclosed in an outer casing B, which-dips into water in'a vessel 0.
In the downcomer A, I suspend a barbed or twisted wire D, or it might be a rod or chain having numerous projecting points, or in the case of a large downcomer I may suspend several such wires, rods, or chains. The vessel G is made with sloping sides to facilitate the raking of deposit out of it. It is kept supplied with sufticient water to maintain a liquid seal, preventing entrance of air.
The wire, rod, or chain D, or'each of these when several are used, is attached to a crosshead E, which is supported on columns F, of insulating material,and is connected by a conductor G to one terminal of a source of electricity such as can furnish currents of very high tension, as may be obtained from an electrical machine or from a dynamo and high-tension transformer.
The upper part of the wire, rod, or chain is inclosed within a tube T, of non-conducting material. I l
As the electricity is discharged from the barbs or points the particles suspended in the descending gases become separated from the gases and are deposited in the vessels 0, while the more or less purified gases ascend the annular space between the downcomer A and the casing B to an outlet 0, whence they are conducted to any place where they are to be very high tension of the currents employed causes the latter to dissipate rapidlyfrom the points of the wire D and pass into the atmosphere in the downcomer A.
The upper part of the suspended conductor D is attached to a ball or other rounded body E, mounted on the cross-head E, inorder to prevent loss of electricitydue to leakage into the surrounding air from sharp angles or corners, which is a characteristic of all hightension currents.
The course of the gases which enter from the passage 0 at or near the top of the downcomer A is shown by arrows. through the latter they pass into the annular space between the downcomer A and the outer casing B, and near the top of the latter they find egress through a passage 0'. J
Having thus described the nature. of this invention and the best means I know of carrying the same into practical effect, I claim 1. In an apparatus for separating dust from blast-furnace gases, the combination with a downcomer having a surrounding casing with an annular intervening space for the gases and fumes, of a vessel containing fluid in which the lower end of the surrounding casing is submerged, a conductor of electricity suspended centrally in the downcomer and provided with projecting points, and a generator of high-tension currents of electricity, the'lower end of the downcomer lying above the level of the fluid in said vessel, substantially as described.
2. In an apparatus for'separating dust from blast-furnace gases, the combination with a downcomer and with a concentric surrounding casing, of a vessel having sloping sides and containing fluid in which the lower end of the said casing is submerged, a conductor of electricity suspended centrally in the downcomer and provided with numerous project After flowinging points, and a generator of high-tension In testimony whereof I have hereunto set currents of electricity, the lower end of the my hand in presence of two subscribing witdowncomer lying above the fluid in said Vesnesses.
sel to permit the gases an d fumes to pass into BENJAMIN IIOWARTII TIHYAITE. the annular space between said downconler XVitnesses:
and the surrounding casing, substantially as OLIVER IMRAY,
described. J NO. P. M. MILLARD.
